Clear Skies Offer Opportunity to View Perseid Meteor Shower in East San Diego County

Clear nighttime conditions are forecast through at least the middle of next week, providing favorable circumstances for observing the annual Perseid meteor shower in San Diego County. The event will reach its peak late on August 12 and in the early hours of August 13, but NASA notes that visibility may be limited at that time due to the moon being about 84 percent illuminated.

The best viewing locations are in the county's eastern foothills, mountains, and desert areas, where there is less light pollution and a broader view of the sky. Meteors can appear anywhere above the horizon, though many observers prefer to face northeast toward the constellation Perseus. The optimal viewing window is from midnight to just before dawn, and experts recommend allowing 20 to 30 minutes for eyes to adjust to the darkness.

Meteor activity is caused by ice and dust from Comet Swift-Tuttle entering Earth's atmosphere and burning up. Viewing from coastal communities is expected to be challenging due to significant light pollution and an overnight marine layer that could reach at least 700 feet deep, according to the National Weather Service.
